Hello there,

I would to ask if there are some option or way to control 3 Relay switches on Mach3?

And which board I need to use?

Thanks so much!

Yes, you can control as many relays as you have available outputs. I use the different outputs to control flood coolant, auxiliary spindle cooling fans, etc.

Wire your outputs to the solenoid that switches the 110v on and off and then set the outputs in Mach3 accordingly.

Thanks you so much man!
I have asked this because i want to make oxy fuel under Mach3 control.
Did you use mach3 for plasma or for what kind of machine?

X2 mini mill.

MAKE Oxy Fuel? Now that's a usage of Mach3 I've never heard of.

This community continues to amaze me!

Yeah man, oxy fuel! It's your first time you hear?
